Add Ubuntu workstation into your Windows Active Directory

The good points about this kind of setup is as follows:

Single username/password combination across entire network.

Enforces password policies

Likewise Open enables Linux, Unix and Mac authentication on a Microsoft network using Active Directory. A user can now interactively log in to the Linux, Unix or Mac machine using Active Directory credentials, and can access any kerberized services that the non-Windows machine hosts can.

sudo /etc/init.d/likewise-open start

If you want to get rid of the UBUNTU\ part…
edit the following file:
“vi /etc/likewise/lsassd.conf”
Find the line that says “assume-default-domain”
and set it to true or uncomment depending on the version of likewise.

It’s best to reboot after this just to deal with the change.

PS. This only works when your user account and computer account are part of the same domain.
